Reddit mentions of Clan Novel Nosferatu (Vampire: The Masquerade Clanbooks)

My personal belief is that you should probably make it up for yourself. Anatole as a character, like most of the Metaplot characters, didn't have much time dedicated solely to himself. His actions didn't usually unravel like a novel, but more like a history book after the fact so it's tough to get a real handle on him. That said, I'll try to help out with Anatole as a character as best I can.

The first thing that sticks out in my mind are the Clan Novels. They're a series of 13 books, one for each Vampire Clan, that serve as a prelude to Gehenna. Anatole is featured as one of the narrative POV's, SPOILER ALERT and it details his death. END SPOILER ALERT. It's been a long, long time since I read the books so I can't really speak to the quality of the writing, but I do remember I enjoyed many of the plot points which include some of my favorite metaplot characters such as Cardinal Moncada, Anatole and of course Theo Bell.

Th next obvious choice would be Clanbook: Malkavian, especially the revised edition, which touches on many of the Malkavian Specific plot points, such as the Malkavian Madness Network which is the clan's shared consciousness. There's even a special merit, called Disembodied Mentor, that represents another Malkavian who has died, but whose consciousness lives on through the Network and can serve as a ghostly advice giver. It also has a brief account of Anatole's life, although it doesn't have any specific writings about his prophecies.

If I remember right, some of the Dark Ages books such as the Libellus Sanguinus clanbooks have letters and narratives written by Anatole, but I don't remember specifically what they entail.

What I can relate about Anatole from my own recollection(which is not perfect) is that, first and foremost, he possessed True Faith. He was able to perform small narrative miracles such as consecrating ground against other Vampires. He was nearly a thousand years old and a rampant Diablerist, performing it at least four times to jump from 10th generation to 6th generation. One of those Diableries was of a demon-possessed Malkavian named Octavio, and when he devoured the soul he also took on the possession of Kupala who was an Eastern-European land spirit who also gave the Tzimisce their Koldunic Sorcery powers. He was a colleague of Beckett, the Book of Nod scholar, and had something of a professional rivalry with the Tzimisce Sasha Vykos who was a fearsome Priscus in the Sabbat. As far as personality goes, he often came across as dire and aloof, classically not grounded in reality, reacting to things that nobody else saw, or that may not have even happened yet. He heard the (supposedly) real voices of Octavio and Kupala, as well as the voices of religious figures who all spoke to him about Gehenna and his role in it. Like most prophets and Malkavians, he doesn't really speak plain. He uses metaphor extensively, and says things that, at present, may seem like nonsense, but become useful in their own time.

If you have any more specific questions feel free to ask, although like I said my memory isn't the greatest so I may not have immediate answers, or the answers I do have will be tinged by what I imagined about Anatole rather than read ; D
